IMPROVEMENT IN MACHINES FOR CUTTING BARREL-HOOPS.

Specification forming part of Letters Patent No. 57,120, dated August 14, 1866.

To all whom it may concern:

Be it known that I, ANDREW GooDYEAR, of the town of Springport, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Machines for Making Hoops for Barrels, or for analogous uses; and I do hereby declare that the following is a full, clear, an d exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in whichy Figure lis a side elevation. Fig. 2 is a crossscction in the line x and elevation of one end of the machine. Fig. 3 is an enlarged section of a portion in said line x. Fig. 4 is a partial elevation of cutting-knife detached. Fig. lis broken to indicate disproportionate length.

Similar letters of reference indicate correspondin g parts in all ofthe figures.

My invention relates to a mode of cutting hoops for barrels from boards, so as to leave one edge thinner' than the other, to adapt it to the bilg'e, or for cutting lath with beveled edges, which, when nailed to the wall, will leave dovetail-formed spaces between them, so as to better secure the plaster, or for other analogous uses.

The invention consists in the use of a simple lever acting on a sliding hinged table against a clamped horizontal or oblique cutter, in connection with arrangements for properly tilting said table and for safely discharging any article, when cut, from the machine; and the better to enable others skilled in the art to construct my said invention, I will now proceed more particularly to describe it.

My mode of cutting resembles the mode in usefor cutting staves, a board of proper thickness well steamed being-forced up against a thin cutting-knife substantially in the manner of a stave-bolt. 'Io avoid, therefore, any redundancy of language, I propose to limit my detailed description to such arrangements of parts only as form distinctive features in my machine for the special uses indicated.

As I usually construct my machine, a strong cutter-beam of cast-iron, A, bolted to two standards, B, constitutes the frame. The cutter-beam may be secured by adjusting bolts b through the flanges f, and made adjustable laterally by slots in the standards. The beam is formed in two halves bolted together, between which the cutter-knife O-a long, thin, sharp-edged plate of steelis firmly pinched.

To prevent the cutting-knife C from springing I cast openings o and side grooves in the beam-plates, in which grooves the nuts n are inserted, provided with set-bolts c, which form a solid backing for the knife, and can be screwed down to compensate for wear.

I do not wish, however, to confine myself to setting the cutting-knife exactly parallel with the board to be cut; but, when necessary. I propose to so connect such knife and its beam with the standards as to form any suitable angle for the purpose of giving more or less of a shearing-cut, in which case said knife would be fastened by countersunk headed screws flush with the face of a single solid beam, as may be clearly seen in Fig. 4, where C2 represents the knife.

D is a vibrating lever, cast ont or otherwise secured to an angle rock-shaft, E, having its bearings r in the standards, and operatin g, by any desired number of pressure-bars, F, a sliding platen, H, which is guided in the grooves Gr.

T represents the feeding table, on which the stui' to be cutrests. It is simply a flat iron plate hinged to the platen in close contact, immediately below the cutting-knife, and when used, as in Fig. l, a narrow groove, g, should be formed near the back edge, and filled with a strip of wood, as a line of contact with the said knife when finishing the cut.

Inorder to give the proper bevel or taper to the article cut without the trouble of turning over the board, I elevate and depress the feeding-table alternately from a horizontal line, just previous to each cut, in the following manner: To one end of the sliding platen H is connected a projecting arm, J, which carries two spur-wheels, S and S2, gearing into each other and revolving freely upon studs secured to said arm. The wheel S is only half the diameter of S2, and has a small fly-wheel, W, cast or otherwise attached to it, which fly carries a crank-pin, p, so as to be capable of adjustment for any required length of stroke. A rod, It, free to vibrate on the projecting armpin at o, is connected to the said crank-pin by a strap in the ordinary way.

The Wheels are so arranged that the front part of the hinged feeding-table will rest upon the ed ge Of a cam-plate, 2, fasten ed to the Wheel S?, the semi-periphery of which plate projects a distance equal to the required lift of the table. The cam-shaped projecting portion may ment will, aided by the centrifugal force gen-Y erated by the fly, produce a con tinuous motion of .the gear, the cani making a senti-revolution for every whole revolution lof the crank-pin or corresponding up-and-down motion of theA cutting-knife, and thus elevate and depress the table alternately at every cut, so as YtO change the an gie ofthe board with the line lof motion of the platen, and, without shifting the hoard, produce a hoop, lath,or other article, with one edge or side thinner or narrowerthan thefother.

L represents guide or gage rods, attached 4to an adjustable bar, M, to gage the thickness of the article to be out, and to prevent such article from dropping back on the table after being cut I attach to the guides a spring, j, the

Operation of which is clearly'shown :in Fig. 3.

Theedge of a hoard, N, beingpressed against the springs, forces them back in to .recesses (not shown) in the guides, and comes in contact with them; the platen, lifting the -boardfagainst the cuttingknife C', cuts off a hoop, It, Wihen the spring recovers its first :position and -s-u-pports the hoop on a flip until thenexteutzhoop pushes :it Off and takes its place, 8vo.

The vibrating lever D may be operated by a pitman (not shown) connected at one end to the adjustable pin P, and at the other to the adjustable pin of a crank driven by any requisite and convenient motive power. By applying the cam i to lone edge of atable arranged to vibrate horizontally, and a spring to the other, shingles may be readily out in my Inalchine, or any article having' slight horizontal angles.

l do not claim cutting hoops or other articles from a steamed board by forcing such board against a stationary knife, so as to make either a direct or shearing cut; nor do I claim, broadly, tilting or vibrating the table on which such board lies.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The use of the eamt, incombination with the gear-Wheels S S2, ily-Wheel W, and vi- ;brating rod R, arranged and operated, relatively with each Vother and with the platen, table, and frame, substantially as and for the fuses specified.

2. The Inode of securing the cutteiuknife C by clamping it between the half-beams A, in combination with hacking-.bolts e and nuts n, substantially as herein described.

3. The employment of aspring, j, in combination with recessed guides L, for safely discharging a hoop, h, oriother out article, as set forth.
